This paper explores the potential use of endocannabinoidome molecules as a therapeutic approach to treating traumatic brain injury (TBI). Google Scholar was used to obtain the primary research literature analyzed for this review. Studies which manipulate the endocannabinoid system through methods such as administration of 2-AG or AEA ligands, inhibiting breakdown enzymes, and using CB1 and CB2 agonists or antagonists have shown promising results in treating TBI; however, no pragmatic clinical therapy has been found so far. The discovery of similar molecules and receptors has resulted in the expansion of the endogenous system and bred the term endocannabinoidome, which incorporates the newly discovered molecules and receptors. Ligands of the endocannabinoidome produce similar therapeutic benefits for TBI but act by different receptor pathways, which may allow one to overcome current existing problems of manipulating the endocannabinoid system for TBI treatment. Currently, therapies used to treat TBI have many unwanted side effects, establishing the need for alternative research options. This paper examines three of these endocannabinoidome molecules that have been previously researched for treating TBI and illuminates their specific receptor pathways and how these receptor pathways operate differently from the ordinary pathways of the endocannabinoid system. Gaining an understanding of the receptor pathways used by endocannabinoidome molecules will open a new field of research for therapeutics to treat TBI.

Studies have reported changes in the endocannabinoid system in the brain of patients with Alzheimer's disease (AD), playing a role in the pathophysiology of AD. Cannabinoids have been shown to have neuroprotective properties, reduce neuroinflammation, and enhance neurogenesis. Evidence suggests that the utilization of marijuana products containing both tetrahydrocannabinol (THC) and cannabidiol (CBD) or CBD alone have been effective and safe for use in older people with agitation associated with dementia. A review in 2017 summarized positive findings for therapeutic benefits of cannabinoids in agitation of AD and dementia, but there was no definitive conclusion because of varying cannabinoid products. Cannabinoids were shown to be well tolerated, with few short-term side effects. This differs from first-line medications utilized for dementia behaviors, which can have unwanted side effects. Further research regarding the safety, efficacy, and variability of these products in older people is needed.

This review summarizes the epigenetic mechanisms of deoxyribonucleic acid (DNA) methylation, histone modifications in cancer and the epigenetic modifications in cancer therapy. Due to their undesired side effects, the use of epigenetic drugs as chemo-drugs in cancer therapies is limited. The drug delivery system opens a door for minimizing these side effects and achieving greater therapeutic benefits. The limitations of current epigenetic therapies in clinical cancer treatment and the advantages of using drug delivery systems for epigenetic agents are also discussed. Combining drug delivery systems with epigenetic therapy is a promising approach to reaching a high therapeutic index and minimizing the side effects.

Background: Thymol is a natural phenolic monoterpenoid widely used in pharmaceutical and food preservative applications. Thymol isomeric with carvacrol, extracted primarily from Thymus species (Trachyspermum ammi) and other plants sources such as Baccharisgrise bachii and Centipeda minima, has ethnopharmacological characteristics. <p></p> Methods: This review was prepared by analyzing articles published on thymol moiety in last decade and selected from Science Direct, Scopus, Pub Med, Web of Science and SciFinder. The selected articles are classified and gives brief introduction about thymol and its isolation, illustrates its natural as well as synthetic sources, and also therapeutic benefits of thymol worldwide <p></p> Results: Thymol has been covering different endeavors such as antimicrobial, antioxidant, antiinflammatory, antibacterial, antifungal, antidiarrhoeal, anthelmintic, analgesic, digestive, abortifacient, antihypertensive, spermicidal, depigmenting, antileishmanial, anticholinesterase, insecticidal and many others. This phenolic compound is among the essential scaffolds for medicinal chemists to synthesize more bio-active molecules by further derivatization of the thymol moiety. <p></p> Conclusion: Thymol is an interesting scaffold due to its different activities and derivatization of thymol is proved to enhance its biological activities. However, more robust, randomised, controlled clinical trials would be desirable with well-characterised thymol preparations to corroborate its beneficial effects in diseased patients. Moreover, in view of the potential use of thymol and thymol-rich essential oils in the treatment of human infections, comprehensive studies on chronic and acute toxicity and also teratogenicity are to be recommended.

Arginine Supplementation

Background: Arginine is considered a semi-essential amino acid in healthy adults and the elderly. This amino acid seems to improve the immune system, stimulate cell growth and differentiation, and increase endothelial permeability, among other effects. For those reasons, it has been theorized that arginine supplementation may be used as an adjuvant to conventional cancer therapy treatments. Objective: This review aims to evaluate the existing knowledge of the scientific community on arginine supplementation in order to improve the efficacy of current cancer treatment. Results: Despite the continued efforts of science to improve treatment strategies, cancer remains one of the greatest causes of death on the planet in adults and elderly people. Chemo and radiotherapy are still the most effective treatments but at the cost of significant side effects. Conclusion: Thus, new therapeutic perspectives have been studied in recent years, to be used in addition to traditional treatments or not, seeking to treat or even cure the various types of cancer with fewer side effects.

AbstractAlcohol Use Disorder (AUD) affects a large portion of the population. Unfortunately, efficacious medications to treat the disease are limited. Studies in rodents suggest that mTORC1 plays a crucial role in mechanisms underlying phenotypes such as heavy alcohol intake, habit, and relapse. Thus, mTORC1 inhibitors, which are used in the clinic, are promising therapeutic agents to treat AUD. However, chronic inhibition of mTORC1 in the periphery produces undesirable side effects, which limit their potential use for the treatment of AUD. To overcome these limitations, we designed a binary drug strategy in which male mice were treated with the mTORC1 inhibitor RapaLink-1 together with a small molecule (RapaBlock) to protect mTORC1 activity in the periphery. We show that whereas RapaLink-1 administration blocked mTORC1 activation in the liver, RapaBlock abolished the inhibitory action of Rapalink-1. RapaBlock also prevented the adverse side effects produced by chronic inhibition of mTORC1. Importantly, co-administration of RapaLink-1 and RapaBlock inhibited alcohol-dependent mTORC1 activation in the nucleus accumbens and attenuated alcohol seeking and drinking.

Therapeutic Benefits

Diabetes mellitus (DM) is a metabolic disorder affecting a large number of people worldwide. Numerous studies have demonstrated that DM can cause damage to multiple systems, leading to complications such as heart disease, cancer, and cerebrovascular disorders. Numerous epidemiological studies have shown that DM is closely associated with dementia and cognition dysfunction, with recent research focusing on the role of DM-mediated cerebrovascular damage in dementia. Despite the therapeutic benefits of antidiabetic agents for the treatment of DM-mediated cognitive dysfunction, most of these pharmaceutical agents are associated with various undesirable side-effects and their long-term benefits are therefore in doubt. Early evidence exists to support the use of traditional Chinese medicine (TCM) interventions, which tend to have minimal toxicity and side-effects. More importantly, these TCM interventions appear to offer significant effects in reducing DM-related complications beyond blood glucose control. However, more research is needed to further validate these claims and to explore their relevant mechanisms of action. The aims of this paper are (1) to provide an updated overview on the association between DM and cognitive dysfunction and (2) to review the scientific evidence underpinning the use of TCM interventions for the treatment and prevention of DM-induced cognitive dysfunction and dementia.

Mobile wireless sensor networks (MWSN) are composed of a large number of mobile sensor nodes, which are used to collect data. MWSN have been widely applied in a variety of harsh environments, so mobile sensor nodes are often at risk of damage. How to manage mobile sensor nodes is an important issue. In this paper, we analyse different mobility management schemes proposed in some typical research literature and classify these schemes by using three features: the collaboration between mobile sensor nodes, routing and deployment in MWSN. We specify advantages and disadvantages of the proposed schemes, compare different key parameters of MSWN respectively, including energy efficiency, data delay, cost and lifetime, etc. Finally, we discuss existing problems of MWSN management and give some helpful suggestions in this area.

Pre Service Teacher

Much of the coursework in pre-service teacher education programs focuses on “best practices” in classroom teaching that span from general pedagogical knowledge and pedagogical content knowledge (e.g., methods, management, assessment, etc.), in addition to supervised practica and student teaching experiences. Given that pre-service (and in-service) education students are being prepared for a career in teaching, coursework should also prepare them to understand, critique, and adapt to changes in best practices that occur over the course of their careers. The authors argue that one of the best ways to prepare students for changes in educational practices is to help them understand where best practices come from in the first place—primary research in education. Reading, thinking critically about, and applying the findings from primary research articles can improve the professional development of pre-service teachers. The goals of this chapter are to 1) provide a review of the benefits of requiring primary research articles as required readings in undergraduate curriculum, 2) underscore the argument for why primary research should be included in pre-service teacher education curriculum, and 3) offer a model for how this could be implemented in a pre-service teacher education curriculum.
